Dermatology Online Journal became the first medical open access journal in the early 1990's. Today, thousands of open access medical journals are available on the Internet. Despite criticisms surrounding open access, these journals have allowed research to be rapidly available to the public. In addition, open access journal policies allow public health research to reach developing countries where this research has the potential to make a substantial impact. In the future, open access medical journals will likely continue to evolve with technology, changing how medical research is accessed and presented.
